top and place a burner cap above the said In carrying out the present improvement dish and provide the said disk with a I utilize a main burner housing l having valved opening operative from the outside projecting horizontally from the rear side as of the burner whereby the valve may be the combined vapor and air receiving device opened for supplying vapor or fuel to the 2. The housing 1 has a transversely arburner cap or the valve closed and the vapor ranged channel 3 in which a generator tube 4riiii flow from the chamber in the lower part of of the type described in the aforesaid applithe housing to either the oven burner or cationis located. Below this generator is a 00 another burner or to both burners, or to all torch holding device 5 for receiving a torch three burners simultaneously. (not shown) for initially heating the generait further object of the invention is to tor tube l. All of the foregoing members provide an obstruction between the burner are constructed like that shown in the above cap and the said disk located at the valve referred to application except in some parts opening in the disk, the said obstruction that will be described hereinafter.

serving to spread the vapor uniformly under a One of the features of the present inventhe burner cap openings, instead of flowing tion is to provide an oven burner 6 that directly through the adjacent burner cap communicates through a conduit 7 with the openings, whereby the vapor flows evenly lower part of the housing 1. Furthermore through all burner cap openings. a burner 8 as here shown is located in rear tlther objects of the invention will. appear of the main burner 1 and this burner 8 comfrom the following description of the conniunicates with the opposite side of the lower till struction. and operation of the burner and part of the main burner through a suitable its several parts. conduit 9. 1

in the drawings: As shown the main burner is provided Figure l is a top plan view showing an with a division plate 10 that forms the to arrangement of the improvements the frame for the housing of the burner. This divitar - controlled by a suitable valve 15.

sion plate therefore, forms a large chamber 11 intowhich the vapor generated by the generator tube 4 flows and from this chamber 11 vapor flows into the conduits 7 and 9 and to the oven burner 6 and to the rear burner 8. A very shallow chamber 12 is located between the burner cap 13 and the division plate or top 10. For the purpose of controlling the amount of vapor that may flow from the chamber 11 into the chamber 12 and thence throughthe openings in the burner cap 13, this'di-v'ision plate isprovided with an opening 14, the said opening being This valve reeiprocates vertically and therefore moves upward to close or 'partlyclose the openin 14 or moves downward for the p urpose o wholly opening or'partly opening the communication with the shallow chamber 12. For the purpose of providing a convenient manner of operating the valve 15, I provide it wit-h a depending stem 16 that passes downward through a suitable sleeve 17 and to a point below the bottom of the chamber 12. An oscillating shaft 18 is journaled in the ends of a U-shaped bracket 19. Located on the inner end 20 of a shaft 18 are an eccentric pin 21 and a cam 22 that engage a lateral U-shaped member These members operate to move the stem 17 up and down and therefore to move the valve 15 correspondingly.

For the purpose of heating the generator tube, the top of the transverse channel 3 is provided with a plurality of transverse slits 24 through which vapor passes downward from the shallow chamber 12 where air'is combined with it to supply combustion for heating the said generator tube.

For the purpose of controlling the flow of va or to the burners 6 and 9', I provide vaives 25 that are moved in and out in .respeet to the inlet end of the conduits 7 and 9; These valves are attached to the inner ends of U-shaped members 26, one of the legs of the U being provided with a line of perforations 27 that engage with a suitably shaped gear wheel 28. Attached to each of these gear wheels 28 are rods 29 carrying at their outer ends suitable handles for rotating the parts. It will be observed that by turning the handles 30 the valves 25 can be caused to move to either closed or open position, for controlling the flow of vapor from the chamber 11 through the conduits and to the respective burners 6 and 9.

From the foregoing description it will be understood that the burner is started by means of a suitable torch (not shown) that- 'is saturated with gasoline and is lighted and placed in the liolder 5,'the flame vfrom the gasoline assing upward and striking the enerator tu e 4. After the tube has become eated, then by turningfthe valve 31, the vapor will flow through the passage 2 as described in the above referred to application, and fills the large chamber 11 of the housing 1. It it is desired that the main burner should be operative, then the valve 15 is open to the proper extent to permit the vapor to flow from the chamber 11 into the chamber 12 and thence through the slits 232 of. the burner cap 13. Likewise the tlow of vapor can be controlled to the burners (i and 9 as previously stated. If it is desired to burn either the burner (i or the rear smaller burner 8 without operating the main burner. then the valve 15 is moved upward and the opening 14. closed which will shut oil' the flow of vapor to the main burner and extinguish it. At the same time, however. vapor flows from the large chamber 11 through the passages 13 and downward, into the transverse passage 13 where air mixes with it. causing it to burn and to continue to heat the generator. This burning llame is operative all the time thatthe generator is turnishing vapor, and that is true whether the main burner is operating or not.

The broad principle therefore, of operation of this improved burner is to provide a plate that divides the housing into a distributing chamber 11 and a separate chamber 12, the chamber 12 serving to supply vapor to the main burner and the chamber 11 serving to supply vapor to the ide burners. This division plate is so constructed that when the valve 15 is closed. then the chamber 12 thereabove is wholly closed to any communication whatever with the chamber 11 and at the same time vapor is led to the passages 21 made in the top of the transverse channel 3 for providing a continuous flame for continuously heating the generator tube.

I find it highly desirable to provide some means located between the opening It and the burner rap to cause the vapor to [low through the burner cap to spread laterally and fill the whole shallow chamber 12 and thereby supply 'apor to all of the burner slits 32 of the main burner. \Vithout some provision for causing the vapor to sprearh there would be tendency to have a heavy flow of vapor through these slits located nearest the opening 14-, whereas it is highly desirable to have all of the slits provided with substantially a uniform {low of the vapor.

Therefore in the form here shown, 1 have provided an obstruction which consists oi a plate 38 that is located between the adjm cent main burner slits that serves to spread the aper in the chamber 12.

Preferably the burner caps oi the main burner and the burner 8 are arranged to provide parallel series ot passages. that are formed in upwardly extending projertions 34.

The special construction of the oven burner till till

tilt

consists in providing this burner with its two sides 35 and its ends 36 each having their bottoms slit as shown at 37 in Figures t and 'i'. The ends oi. the parallel parts communicate with a manifold 38 whereby vapor is fed from the conduit 7 into one end oil. the manifold which conveys it to the burner, the tiame burning from the bottom and naturally spreading at each side of the parts 35 and 36 and flows upward to heat the oven For the purpose of tl'acilitating the light ing oi? the burners, I provide means for conveying the tire from the respective burners for the purpose of lighting any desired one oi the three.

it suitable lighter 39 is located between the burner 8 and the main burner 1 and a lighter at) is located between the main burner and the oven burner 6. The lighter 39 consists of a tube ll that has its outer end 43 con'iniunicating with the burner 8, the said tube having its upper portion provided with a longitudinal slit ll and a surrounding larger tube d5. Hence when the vapor flows into the tube ll, it will catch from the top of the main burner and the lire will flash backward to the vapor flowing through the slits 8d oi the burner 8 and lighting it. The larger tube 45 is merely as a protection for the ilame therein, and the tube 41 is attached cecentrically to the tube 45.

'llhe lighter between the main burner and theoven burner 6 consists of the said outer tube or trough portion 40 and an inner tube d6 that has a series of transverse slits 4ST extending throughout its length. Centrally this lighter all connnunicates with the conduit-f? as shown by dotted lines 48. Hence when the valve is open for the flow of vapor to the oven burner 6, vapor will how to the inner tube 46, through the slits 4L7 lighting at the generator and then flashing baclrward and lighting the oven burner.

it will be understood that when the genorator is working and the main burner not lighted, then the main burner can be lighted by opening the valve let causing then the vapor to flow through the slits 32 when it will be lighted from the inner end of the lighter tlt li l hen the generator is working, one bin-neican be lighted from another burner.

In Figure 1 I show in dotted lines 49 the outline of a stove and by dotted lines 50, the outline of an oven in which the oven burner is located. The member at the left of the oven is usually termed the open burner iraine. I desire it understood that the burners may be arranged in any suitable relation to the main burner. That is to say the burners in the open part of the stove may be arranged as in ordinary gas stoves, and the communication 7 may be made to the center of the oven burner. In view of this, various changes will present themselves to those skilled in the art without departing from the spirit and scope of a fair interpretation oi. the appended claims.
